In 1812, Francis Louis Barrallier was ordered to undertake an elaborate military survey of Barbados. The work took him five years. The edition used on this website is that of 1825 and is a digital copy of the map held by the National Archives.
Barrallier identified 416 estates and their owners on a map striking for both its detail and the clarity of its image. The locations of 109 estates given on the map have been linked into the estate details in the database.
